How is this source relevant to your thesis and purpose?

Many emerging writers struggle with connecting sourced material to their claims and to their thesis. Oftentimes, this is because they’re too close to their work and think that the connection between claim and evidence is completely apparent to the reader.

Even if the connection is readily visible, authors should still follow up a piece of sourced material with an explanation of its relevance to the author’s point, purpose, and/or thesis. Such connections (“analysis”) should be made directly following the sourced material.

Main points:

The known economic impact of past oil spills

The potential impact of oil spills on marine and human life

A comparison between advantages and disadvantages of offshore drilling
